ABSTRACT:
Stretched surface recording disk (SSR) 10 comprising an annular support 12 having raised annular ridges 28 and 42 at its inside and outside diameters 22 and 30 with a base portion 24 in between the two ridges, and an annular recording medium film 14 held in radial tension and stretched across the base portion by adhering the film to attachment surfaces 48 and 36 near the inside and outside diameters respectively. The bond between the recording medium film and the support at the inner and outer attachment surfaces is formed by an electron beam cured adhesive such as a mixture of hydantoin hexacrylate and dimethylacrylamide. By manufacturing the stretched surface recording disks with the e-beam process, significantly less time is required to adhere each stretched recording medium to its support, and the quality of the bond between the support and recording medium film is improved. SSR are capable of higher bit density than floppy disks of equivalent surface area and are not as sensitive to contact between the media and a flying magnetic head ("head crashes") as rigid disks.
